Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Engineers built a nanoscale optical device that uses voltage to control light's phase and intensity, advancing quantum communication and compact optical technologies. The device, developed by ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Currently, Kyocera’s technology enables aerial images whose focal positions vary by wavelength. In the future, increasing the ...

Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

Harvard researchers have found that silica, long thought to lack the right properties for optical metasurfaces, can sometimes ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a ...

The seamless integration of optical systems into medical devices presents both unique challenges and significant opportunities.

Optical isolation and nonreciprocal devices are pivotal components in modern photonic systems, ensuring unidirectional light propagation and safeguarding sensitive equipment from unwanted reflections.

Scientists have created an optical device capable of mimicking black holes and the still hypothetical white holes. This system could revolutionize our understanding of the Universe and lead to ...
